DOOR-HANGER AND THE LIKE.

Specification of Letters Patent.

Application filed March 26, 1915. Serial No. 17,198.

To all whom it may concern:

Be it known that I, GEORGE ELMER STERN- BERGH, a citizen of the United States of America, and resident of 24:58 Mance street, in the city of Montreal, Province of Quebec, in the Dominion of Canada, have invented certain new and useful Improvements in Door-Hangers and the like; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to improvements in door hangers and the like as described in the present specification and illustrated in the accompanying drawings that form part of the same.

The invention consists essentially of the novel form and location of the bearings for the trunnions of the wheel or roller supporting the weight.

The objects of the invention are to devise a means of retaining the supporting wheel always in its bearings, so as to avoid loss and displacement, to insure a smooth running door, especially for railway cars, to economize in the maintenance of railway freight cars and generally to provide a simple, cheap and durable device.

In the drawings, Figure 1 is an elevation of the hanger in its most approved form.

Fig. 2 is a fragmentary view showing an enlarged vertical sectional view of the operating parts and tracks on the line AB.

Fig. 3 is an enlarged horizontal section on the line CD in Fig. 1.

Fig. 4 is a rear-elevation of the hanger showing the wheel closed in by a hood at the top end.

Fig. 5 is a vertical sectional view on the line AB in Fig. i.

Like numerals of reference indicate corresponding parts in each figure.

Referring to the drawings, 1 is the body of the hanger, secured to a door at the top end and having the offset 2 toward the upper end from which extend vertically the outer and inner walls 3 and 4: respectively forming a wheel casing open at the top and bottom, said walls having intermediate of their height and directly facing one another in the inner sides, the elongated recesses 5 and 6, said recesses being curved at each end, and between said curved ends having substantially straight and parallel top and bottom bearing surfaces 7 and 8.

The trunnions 9 and 10 of the wheel 11 extend into the recesses 5 and 6 respectively and remain there permanently and roll forwardly and rearwardly on the bearing surfaces 7 or on the bearing surfaces 8, the said wheel running on the track 12, when bcaring on the surfaces 7 and on the track 13, when bearing on the surfaces 8, the said tracks being the flanges from a combined channel and Z-bar 14:. The bar 1 1 is rigidly secured to the car wall above the door opening and therebeyo-nd and receives the wheel between the tracks 12 and 13 so that said wheel may engage either of said tracks according to the movement of the door.

In Figs. 4 and 5 the open top end between the vertical walls is spanned by a hood 15, thus closing in the wheel at the upper end for that particular type of hanger.

The hanger in operation runs as explained on one or other of the tracks 12 and 13, that is to say normally it is resting on the track 12, but in the rough usage incidental to car doors frequently the wheel comes in contact with the track 13 and this materially eases the operations of opening and closing.

The trunnions of the wheel are permanently placed in the recesses during casting and therefore become part of the main body and cannot be separated therefrom. There may be other applications to which this invention can be put and changes in the construction, but the salient feature will remain, that is the retention of the trunnions permanently in the elongated bearings.

hat I claim is:

A door hanger comprising a body portion having a wheel housing at its upper end whose side walls are of substantially the same width from top to bottom and spaced apart to fit the wheel and which have elongated laterally outwardly extending hollow portions opening inwardly to form oppositely disposed trunnion recesses, said side walls including their hollow portions being llnPGl'fOlfltG, and. :1 Wheel permanently l0- catecl 111 the housing and having integral Signed at the city of Montreal, Quebec, Canada, this fourth day of: February, 1915.
